I'll put it very succinctly, for the umpteenth time: there is no such thing as free trade, despite what some libertarian-leaning economists (You can scarcely get a libertarian to admit that the government has a legitimate power to tax at all, let alone get them to admit that tariffs are legitimate.) will tell you, despite what libertarians who would love for you to believe that free trade is a "bedrock conservative principle" will tell you. Other countries find ways to protect their markets. That's the reality.
